The MODIS instrument onboard NASA's Terra satellite captured this true-color image of Tropical Cyclone Gafilo churning in the waters northwest of Madagascar on March 6, 2004. At the time this image was taken, Gafilo has sustained winds of approximately 160 mph. Cyclone warnings had been posted for all of northwestern Madagascar.
The Dvorak technique was developed from early satellite images of tropical cyclones to determine real-time a tropical cyclone's strength from characteristics seen on satellite imagery. In most tropical cyclone basins, use of the satellite-based Dvorak technique is the primary method used to determine a tropical cyclone's maximum sustained winds.
Common developmental patterns seen during tropical cyclone development, and their Dvorak-assigned intensities. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared ...
The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
Infrared satellite imagery can be used effectively for tropical cyclones with a visible eye pattern, using the Dvorak technique, where the difference between the temperature of the warm eye and the surrounding cold cloud tops can be used to determine its intensity (colder cloud tops generally indicate a more intense storm).

Tropical Depression 18 was expected to strengthen as it moved across the Atlantic, the National Hurricane Center said on Thursday, September 23.The center said the depression could become a ...
Terra (EOS AM-1) is a multi-national scientific research satellite operated by NASA in a Sun-synchronous orbit around the Earth.It takes simultaneous measurements of Earth's atmosphere, land, and water to understand how Earth is changing and to identify the consequences for life on Earth. [1]
Meteorologists use these maps to estimate a system's initial position based on aircraft, satellite, and surface data within surface weather analyses. The data is then analyzed to determine recent storm motion and create and convey forecast tracks, wind swaths, uncertainty, related watches, and related warnings to end users of tropical cyclone ...
